ELAVL4 and neuroma: The apoptosis image and quantitative analysis results of flow cytometry indicate that after adding the HuD antibody, the apoptosis level of neuroma cells co-cultured with monocytes increased significantly (P < 0.001), but when neuroma cells were not co-cultured with monocytes, the apoptosis level of neuroma cells did not change significantly after adding the HuD antibody (Figure 1).
